Actually I shouldn't have time to write another story as I should read for my exams but well, I have stupid habit of desain characters. This one started as I read Greek's history and I started think of Spartan girl's story. It however would have sounded too war-like(again) so I changed it.(It seems that I have thing for hostages though, I realised it only now afterwards)
I don't know specific location where this story happens, but it's roughly east from aladdin and south from Mulan, Bengali, Indochina, around there.
I haven't and won't put this artikel even nearly as much effort as I did in link but here's the plot in short. (and I mean in very short) Sorry for all grammar errors.

Plot

Sungai is member of river robbers along with her brothers, their leader is very strict and greedy but they manage fine in their group.
One hari they meet a travelling maharaja's son Shri Dalip Sawai, who was going to meet his friend, and they kidnap him. While he was kept as hostage, Shri Dalip hears from bandits some rumors that there's a conspiracy against his friend whom he was going to visit.
After that Shri Dalip escapes and he decides to stop the conspirators. Sungai is sent after him with her little brother, when they catch Shri Dalip he convinces them to help him as he promises to retun their hostage after they have saved his friend.
They head to the capital and after spying the conspirators, they eventually reveal them all to guards. During this Shri Dalip and Sungai fell in love. Sungai decides to let Shri Dalip escape. Mean while other river robbers were followed them as Sungai didn't come back.
Robbers leader is mad at Sungai as she would have let valuable hostage run away and tries to kill her but Shri Dalip sees this and surrenders to be robbers' prisoner again. He also offers to pay anything to save Sungai's life.
The leader agrees but Sungai is also treated as prisoner and the leader doesn't trust her anymore. At night Sungai's brothers help her and Shri Dalip escape as they don't trust the leader would really spare their sister's life, but the leader notices this and stops them when they're trying to get one of the boats.
They fight and finally beat the leader when he fell in river and crocodiles finish him. Sungai's eldest brother gets rest of robber group to their side and he become new leader.
Shri Dalip ask Sungai to marry him, and builds holiday palace to Sungai's halaman awal town so she wouldn't have to leave her halaman awal and family. He also hires robbers to his personal guards.

And they lived happily ever after, the end.

Characters

Sungai

Sungai is one member of river robbers, her parents have died and she has only her brothers. She's quite smart and is great spy but she's been little pahit and distrustful after losing her parents. She acts as tough and heartless but she's really fair and reasonable, reason why she agreed to help Shri Dalip.

Shri Dalip Sawai

Shri Dalip Sawai is son of maharaja, he's very loyal and heroic. He has his own trained elephant, like Phoebus' Achilles -horse. He's little like Eric and Charming.

Brothers

Sungai has three brothers, two older and one younger. They're all nameless because I think it's better if I don't try to made up some names for them. In short: oldest brother is like Sitka and Kale from Sinbad. detik oldest like Denahi atau Frozone from The Incredibles. Sungai's younger brother were with her and Shri Dalip in capital to reveal conspiracy. He likes to tease Sungai. Though youngest, he's not helpless and actually can help his siblings out of trouble few times.

Music etc.

Movie's style atau "spirit" could be like Tarzan's and Lilo and Stitch's which would mean that soundtracks and songs would follow the accurate culture with western adventure film like impacts.
It was hard to think any songs to this as there's not already really any animations atau songs from this location, but there's few.

This could be Sungai's song in capital when she realises that she loves Shri Dalip. In the end of the song she would go to tell him that he can escape.

That one could be at the end where Sungai's brothers and town allow her marry Shri Dalip, it would be really end of the story after when old greedy robber leader has died.

I don't really know if this would be anywhere but it just came my mind over and over when I thought of possible songs. If this would be actual movie, I'd imagine that the soundtrack and songs would sound something like this.
